Why onClickListener doesn't work?

Why onClickListener doesn't work? - android

I create a view which inflates from RelativeLayout and contains some ImageView with an onClick listener on them.
However, it doesn't work, I tried to show a Toast without success.
I misunderstood something about View maybe.
This is my code:
(a fragment contains the view in his XML)
public class Timeline extends RelativeLayout {
private Context context;
private ImageView imageViewFirstStep;
private ImageView imageViewSecondStep;
private ImageView imageViewThirdStep;
private ImageView imageViewEndStep;
private View timelineView;
private int viewWidth;
private RelativeLayout relativeLayout;
private Drawable drawableFirstStep;
private Drawable drawableSecondStep;
private Drawable drawableThirdStep;
private Drawable drawableEndStep;
private RelativeLayout.LayoutParams layoutParamsStep;
private ProcessActivity activity;
public Timeline(Context context) {
super(context);
activity = (ProcessActivity) context;
init();
}
public Timeline(Context context, AttributeSet attrs){
super(context, attrs);
activity = (ProcessActivity) context;
init();
}
public Timeline(Context context, AttributeSet attrs, int defStyle){
super(context, attrs, defStyle);
activity = (ProcessActivity) context;
init();
}
public void init() {
inflate(getContext(), R.layout.timeline, this);
this.context = getContext();
this.imageViewFirstStep = (ImageView) findViewById(R.id.timeline_first_step);
this.imageViewSecondStep = (ImageView) findViewById(R.id.timeline_second_step);
this.imageViewThirdStep = (ImageView) findViewById(R.id.timeline_third_step);
this.imageViewEndStep = (ImageView) findViewById(R.id.timeline_end_step);
this.timelineView = (View) findViewById(R.id.timeline_timeline);
this.relativeLayout = (RelativeLayout) findViewById(R.id.timeline);
}
public void setTimelineImages(int firstStep, int secondStep,
int thirdStep, int endStep){
viewWidth = timelineView.getWidth();
drawableFirstStep = context.getResources().getDrawable(firstStep);
drawableSecondStep = context.getResources().getDrawable(secondStep);
drawableThirdStep = context.getResources().getDrawable(thirdStep);
drawableEndStep = context.getResources().getDrawable(endStep);
imageViewFirstStep.setImageDrawable(drawableFirstStep);
imageViewSecondStep.setImageDrawable(drawableSecondStep);
imageViewThirdStep.setImageDrawable(drawableThirdStep);
imageViewEndStep.setImageDrawable(drawableEndStep);
imageViewSecondStep.setPadding(viewWidth / 3, 0, 0, 0);
imageViewThirdStep.setPadding((viewWidth / 3) * 2, 0, 0, 0);
imageViewEndStep.setPadding(viewWidth, 0, 0, 0);
imageViewFirstStep.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
AtelierFragment atelierFragment = new AtelierFragment();
activity.showTest(atelierFragment);
/*AtelierFragment atelierFragment = (AtelierFragment) activity.getFragmentManager().findFragmentById(R.id.container);
FragmentTransaction fragmentTransaction =
activity.getFragmentManager().beginTransaction().replace(R.id.container, atelierFragment);
fragmentTransaction.commit();*/
Toast.makeText(v.getContext(), "test", Toast.LENGTH_LONG).show();
}
});
imageViewSecondStep.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
imageViewThirdStep.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
imageViewEndStep.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
/*
* set le texte affiché dans les images de la timeline en fonction des string passés en paramètre
* */
public void setTimelineTextView(String Step, TextView textViewStep, int position){
textViewStep = new TextView(context);
textViewStep.setText(Step);
Typeface face = Typeface.createFromAsset(context.getAssets(),
"fonts/TradeGothic-BoldCondTwenty.otf");
textViewStep.setTypeface(face);
}

Expected Result ( Working correctly on Tablet with Android 4.4.2 with below code)
Actual Results ( Tested on multiple phones with OS >= 8.1.0)

I Have tried your code but unable to reproduce this output
For me your code is working fine check the output
Result in Oreo
Result in android pie
Result in android Q
as per my opinion you should use
You should use RecyclerView with GridLayoutManager
Follow this sample code
Add one recyclerview in your activity layout xml file
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="0dp"
android:gravity="center">
<androidx.recyclerview.widget.RecyclerView
android:layout_width="wrap_content"
android:id="#+id/gridRecyclerView"
android:layout_centerInParent="true"
android:layout_height="wrap_content"/>
</RelativeLayout>
Now inside your activity set GridLayoutManager to your RecyclerView
GridLayoutManager (Context context,
int spanCount)
Creates a vertical GridLayoutManager
Parameters
context Context: Current context, will be used to access resources.
spanCount int: The number of columns in the grid
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.GridLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
public class JavaActivity extends AppCompatActivity {
RecyclerView myRecyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_java);
myRecyclerView = findViewById(R.id.gridRecyclerView);
GridLayoutManager gridLayoutManager = new GridLayoutManager(JavaActivity.this, 6);
myRecyclerView.setLayoutManager(gridLayoutManager);
myRecyclerView.setAdapter(new MyAdapter(this));
}
}
Create one adapter class RecyclerView like this
import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
private Context context;
public MyAdapter(Context context) {
this.context = context;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.row_list_item, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
if (position%2==0){
holder.imgBanner.setBackgroundColor(Color.BLUE);
}else {
holder.imgBanner.setBackgroundColor(Color.GREEN);
holder.imgBanner.setImageResource(R.drawable.red_heart);
}
}
#Override

how to solve this. please help.
thanks in advance.

Then you need to change itemView's xml file ,
android:layout_height="match_parent"
instead of like ,
android:layout_height="wrap_content"

Simple change in spirometer_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
....Your design code
</LinearLayout>

I was having problem with the same from such a long time. Then I found a solution that worked for me.
Add a ListViewHelper java class. Here below is code for ListViewHelper.java
package com.molescope;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListAdapter;
import android.widget.ListView;
public class ListViewHelper {
public static void getListViewSize(ListView listView){
ListAdapter adapter = listView.getAdapter();
if(adapter!=null){
int totalHeight = 0;
//setting list adapter in loop tp get final size
for (int i=0; i<adapter.getCount(); i++){
View listItem = adapter.getView(i, null, listView);
listItem.measure(0,0);
totalHeight += listItem.getMeasuredHeight();
}
//setting listview items in adapter
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() *
(adapter.getCount()-1));
listView.setLayoutParams(params);
}else{
return;
}
}
}
And after adding this java file, in your code wherever you are setting adapter to listview, right after that line add the code below:
ListView myList=(ListView) findViewById(R.id.listView);
myList.setAdapter(new ArrayAdapter<String>.
(this,android.R.layout.simple_list_item_1, listview_array));
ListViewHelper.getListViewSize(myList);

Layout of fragment disintegrates when it dynamically replaces framelayout

I have an app with MainActivity that contains a FrameLayout which would be replaced by a fragment based on which item is clicked in the bottom layout. I have a fragment named "bookings" that must appear in the body area when "Bookings" option is clicked. The "bookings" fragment contains a spinner and a button that are placed at the center of screen inside of RelativeLayout. When the fragment's layout is placed directly inside of body of MainActivity, the spinner and button is centered, just the way I want it to be.

Change height of FrameLayout to match_parent from wrap_content
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottompanel"
android:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_frame"/>
</LinearLayout>

You have match_parent in the height for fragment layout. Try changing it to wrap_content and see if it works

Nothing show after use canvas

I am trying to draw lines and rectangles and the line works perfectly, but when I try to draw the rectangles they doesn't show, so I commented the method and put the rectangles in the background of the layouts, but even they didn't show.

line.addView(DoLine);

I have been researching for many many days to find a solution and today i found it, I just needed to change the height of the layout to 40dp
android:layout_height="wrap_content"// change this to 40dp

In the adapter i dont have any strangle, but if you need i copy it here..I try with fill_parent wrap_content etc but nothing works..
Edit: the adapter code:
public class GridAdapter extends BaseAdapter {
private LayoutInflater inflater;
private Activity activity;
private List<String> images = new ArrayList<String>();
private OnDeleteItem mListener;
public interface OnDeleteItem {
public void onDeleteItemClick(String path);
}
public GridAdapter(Activity inyectActivity, List<String> listImages) {
activity = inyectActivity;
images = listImages;
inflater = LayoutInflater.from(activity);
mListener = (ReviewFilesActivity) activity;
}
public void notifyDataSetChanged(List<String> dataImages) {
images = dataImages;
super.notifyDataSetChanged();
}
public View getView(final int position, View convertView, ViewGroup parent) {
GridViewHolder vHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.grid_view, null);
vHolder = new GridViewHolder(convertView, mListener);
vHolder.image.setImageBitmap(ImagesUtilities.decodeSampledBitmapFromResource(images.get(position), 400, 400));
vHolder.path = images.get(position);
vHolder.delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mListener.onDeleteItemClick(images.get(position));
}
});
} else {
vHolder = (GridViewHolder) convertView.getTag();
}
return convertView;
}
#Override
public int getCount() {
return images.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
static class GridViewHolder {
public GridViewHolder(View view, OnDeleteItem listener) {
ButterKnife.inject(this, view);
}
#InjectView(R.id.grid_item_image)
ImageView image;
#InjectView(R.id.deleteButton)
Button delete;
String path;
public String getPath() {
return path;
}
}
}
Edit2:
I did more simply the XML, but the rows dont show.
