Checkbox not visible in Android 4.x but is visible in Android 5+

I have listview which contains textview and a checkbox.
I am showing the ListView in a DialogFragment. The problem is that the checkboxes do not show up for devices(emulator) running Android version 4.1 to 4.4.4. But they show up normally for Android 5.0+. I have been trying to fix this for hours. But no success.
Can someone please tell me what am I doing wrong?

why not just use the text of the CheckBox?
That way your ListView item could just be
<?xml version="1.0" encoding="utf-8"?>
<CheckBox
android:id="#+id/cb_row_item"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:text="Category name goes here"
android:textSize="15sp"/>

I have found the problem. The checkbox color for Android 4.x is black, so it was blending with the black background. Fixed it by using AppCompatCheckBox instead of CheckBox.

ListView clickable

hello guys I'm looking how to make my ListView clickable , i searched in the net but i haven't found the right answer , and this is my code please help me
`public class acceuil extends AppCompatActivity {
ListView listView;
int [] movie_poster_resource = {R.drawable.profil};
String[] patient_names;
String[] temps_rendez;
MovieAdapter adapter;
View view;
Intent intent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_acceuil);
listView= (ListView)findViewById(R.id.listView);
temps_rendez = getResources().getStringArray(R.array.temps);
patient_names = getResources().getStringArray(R.array.patient_title);
int i=0;
adapter = new MovieAdapter(getApplicationContext(),R.layout.patient_name);
listView.setAdapter(adapter);
for (String titles: patient_names)
{
MovieDataProvider dataProvider = new MovieDataProvider(movie_poster_resource[i],titles,temps_rendez[i]);
adapter.add(dataProvider);
}
}
public void onItemClick(AdapterView<?> l, View v, int position, long id) {
if (id == 0)
startActivity(new Intent(this, patient_from_listview.class));
}
public void open_messagerie (View view){
startActivity(new Intent(this, acceuil.class));
}
public void openn_otification (View view){
startActivity(new Intent(this, acceuil.class));
}
public void opena_parametre (View view){
startActivity(new Intent(this, acceuil.class));
}
public void open_calcule (View view){
startActivity(new Intent(this, acceuil.class));
}
}`

You'd call listView.setOnItemClickListener(OnItemClickListener). That sets the class to be called when an item is clicked. It looks like you've already implemented the onItemClicked function, this will hook it up.

This is how you can achieve this
adapter = new MovieAdapter(getApplicationContext(),R.layout.patient_name);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch(position){
// HERE YOU CAN MAKE CASES FOR EACH CLICK
}

Here is my code, how to do clickable listview on Android Studio...

Its ten provinces and three territories extend from the Atlantic to the Pacific.", "Japan is an island country in East Asia, located in the northwest Pacific Ocean.", "The U.S. is a country of 50 states covering a vast swath of North America, with Alaska in the northwest."};

}
the utility class that i tried
public static class ListUtils {
public static void setDynamicHeight(ListView mListView) {
ListAdapter mListAdapter = mListView.getAdapter();
if (mListAdapter == null) {
// when adapter is null
return;
}
int height = 0;
int desiredWidth = View.MeasureSpec.makeMeasureSpec(mListView.getWidth(), View.MeasureSpec.UNSPECIFIED);
for (int i = 0; i < mListAdapter.getCount(); i++) {
View listItem = mListAdapter.getView(i, null, mListView);
listItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
height += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = mListView.getLayoutParams();
params.height = height + (mListView.getDividerHeight() * (mListAdapter.getCount() - 1));
mListView.setLayoutParams(params);
mListView.requestLayout();
}
}
Here are the screenshots url

it works with portrait orientation, but with landscape the firts listview only show the firts element. I want to show all the elements in it. How i can do that? I tried this here and it works with static data but in my case have the problem explained. Is there a problem with the cursor loader? or i miss something in the layout?

are you saving all your variable sate using SaveInstanceState method.

Your myIntent is null in the last condition. That's why crash is happening. So check if the myIntent is null before starting it. Try the following:
if(myIntent!=null){
startActivity(myIntent);
}

Here in grid there is 8 items and As you said you are selecting last postion i.e. no 7 position . and you have declare Intent as a null and while checking condition you didnt set the value of your Intent.
if(position == 7)
{
Toast.makeText(getApplicationContext(), "Pending", 4000).show();
}
Replace above code with this
if(position == 7)
{
myIntent = new Intent(v.getContext(), YOUR_CLASS_NAME.class);
}

click not working on searchitem from listview android

Click on search item inside edittext redirect on wrong activity, it doesn't open the activity associated with it. It opening other activities that are associated with other listitems but not that i am clicking one.
Here is my complete code:
public class Tabtwo extends Activity implements OnItemClickListener {
ListView listView;
TextView txt;
ArrayAdapter<String> adapter;
// Search EditText
EditText edtSearch;
// Array of strings storing country names
String[] countries = new String[] { "Admin Cost", "Affinity Diagram",
"Analyse", "Apprasal Costs", "Assessment of Stakeholders",
};
// Array of integers points to images stored in /res/drawable-ldpi/
int[] flags = new int[] { R.drawable.admin, R.drawable.affinity,
R.drawable.analysis, R.drawable.appraisal, R.drawable.assessment,
};
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabtwo);
// Each row in the list stores country name, currency and flag
List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < 4; i++) {
HashMap<String, String> hm = new HashMap<String, String>();
hm.put("txt", countries[i]);
hm.put("flag", Integer.toString(flags[i]));
aList.add(hm);
}
// Keys used in Hashmap
String[] from = { "flag", "txt" };
// Ids of views in listview_layout
int[] to = { R.id.flag, R.id.txt };
// Instantiating an adapter to store each items
// R.layout.listview_layout defines the layout of each item
final SimpleAdapter adapter = new SimpleAdapter(getBaseContext(),
aList, R.layout.listview_layout, from, to);
// Getting a reference to listview of main.xml layout file
ListView listView = (ListView) findViewById(R.id.listview);
edtSearch = (EditText) findViewById(R.id.Search_box);
txt = (TextView) findViewById(R.id.txt);
listView.setOnItemClickListener(this);
// Setting the adapter to the listView
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(this);
edtSearch.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before,
int count) {
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged();
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void afterTextChanged(Editable s) {
}
});
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
if (position == 0) {
Intent int0 = new Intent(getApplicationContext(), Admincost.class);
startActivity(int0);
}
if (position == 1) {
Intent int1 = new Intent(getApplicationContext(), Affinity.class);
startActivity(int1);
}
if (position == 2) {
Intent int2 = new Intent(getApplicationContext(), Analyse.class);
startActivity(int2);
}
if (position == 3) {
Intent int3 = new Intent(getApplicationContext(),
ApprasalCosts.class);
startActivity(int3);
}
if (position == 4) {
Intent int1 = new Intent(getApplicationContext(), Assessment.class);
startActivity(int1);
} }
}
}
Here is my tabtwo xml file.

Replace your onItemClick method with below and try.. Hope it works..
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
TextView tv = (TextView) arg1.findViewById(R.id.txt);
String str = tv.getText().toString().trim();
if (str.equals(countries[0])) {
Intent int0 = new Intent(Tabtwo.this, Admincost.class);
startActivity(int0);
}else if(str.equals(countries[1])) {
Intent int1 = new Intent(Tabtwo.this, Affinity.class);
startActivity(int1);
}else if(str.equals(countries[2])) {
Intent int2 = new Intent(Tabtwo.this, Analyse.class);
startActivity(int2);
}else if(str.equals(countries[3])) {
Intent int3 = new Intent(Tabtwo.this, ApprasalCosts.class);
startActivity(int3);
}else if(str.equals(countries[4])) {
Intent int1 = new Intent(Tabtwo.this, Assessment.class);
startActivity(int1);
}
}

Add this code to your TextView as well as to ImageView
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
and for ItemClick you can use the answer of Tamilan

I meet the same question with you. Try the following one:
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked, show a toast with the TextView text
//(String) getListAdapter().getItem(position);
String city_id=map.get( (String) adapter.getItem(position) );
Toast.makeText(getApplicationContext(),city_id, Toast.LENGTH_SHORT).show();
Intent i=new Intent(MainActivity.this,DetailActivity.class);
i.putExtra("city_id",city_id);
startActivity(i);
}
});
