I am creating an intent to play videos stored in the sdcard. It happens that I play the first one, everything is OK. But when I play another one, it just plays everytime the first one I played. Here is my code:
package com.remote;
import java.io.File;
import java.io.IOException;
import com.remote.R.drawable;
import android.app.Activity;
import android.content.Intent;
import android.graphics.PixelFormat;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.MediaController;
import android.widget.VideoView;
public class MyVideos extends Activity{
private String path="/sdcard/Movies/Telmex";
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.myvideos);
createLinks(new File(path));
}
public void createLinks(File path)
{
LinearLayout layout = (LinearLayout) findViewById(R.id.myvideoslayout);
if( path.exists() ) {
File[] files = path.listFiles();
for(int i=0; i<files.length; i++)
{
if(files[i].getName().toString().charAt(0)!='.')
{
String videoName;
Button video=new Button(this);
video.setBackgroundColor(2);
video.setTextSize(23);
video.setCompoundDrawablesWithIntrinsicBounds(0,0,drawable.videoicon,0);
videoName=new String(files[i].getName());
video.setText(videoName);
createListener(video,videoName);
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
layout.addView(video,p);
}
}
}
}
public void createListener(Button video, final String name)
{
video.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
videoPlayer(path,name,true);
}
});
}
public void videoPlayer(String path, String fileName, boolean autoplay)
{
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
Uri data = Uri.parse(path+"/"+fileName);
intent.setDataAndType(data, "video/mp4");
startActivity(intent);
}
}
Rewrite
I did some digging and wrote the code below, if this has the same problem then it is your external video player not you app.
public class ExampleActivity extends Activity {
// Change this path
private final String path = Environment.getExternalStorageDirectory() + "/android/data/com.example/files/";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
File dir = new File(path);
List<String> files = new ArrayList<String>();
Collections.addAll(files, dir.list());
Collections.sort(files);
while(files.get(0).startsWith("."))
files.remove(0);
ListView listView = (ListView) findViewById(R.id.list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, files);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String uri = path + ((TextView) view).getText().toString();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(uri), "video/*");
startActivity(intent);
}
});
}
}
Addition
I'm glad the internal video player works. The reason why it resets is that every time you change orientation the OS destroys and rebuilds your app from scratch... It's the same as if you exited the app by pressing the back button and ran it again. If you are using the tutorial from below, you need to save the video's location in onDestroy() to a class variable and in your onCreate() check to see if that variable has a valid location or just start at the beginning of the video.

It can be two differents things :
You've imported android.widget.Toolbar instead of android.support.v7.widget.Toolbar
Your Activity has to extends AppCompatActivity if you want to use setSupportActionBar(toolbar)
If you extends AppCompatActivity you have to use Theme.AppCompat.Light.NoActionBar
#Skizo here everything works fine and extends Activity...

I did solved my issue , I had to include my toolbar layout in my activity layout... Thank you everyone for interest in solving my issue!!
The activity below has an edittext and a search button for the files of Downloads directory,
when I click the button shows me the mp3 files by title in a listview. Now the promblem is that I don't need the edittext and the search button, I want only the listview to show on activity launch. How can I achieve that.

I have implemented an Image Gallery using a GridView displaying thumbnails of images and a Fullscreen Activity which will display each of the images in fullscreen mode. The file paths are passed using Intents (putExtra) to the GridView Activity to display different GridViews depending on folder name in SDCARD.Now the problem I have is that I cannot pass those file paths to the Fullscreen Activity in order to view every image separately.
Below are my Classes ;
MainActivity.java
package info.androidhive.imageslider;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
private Button btn1, btn2;
Intent intent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = (Button) findViewById(R.id.button1);
btn2 = (Button) findViewById(R.id.button2);
setOnClickListeners();
}
public void setOnClickListeners(){
btn1.setOnClickListener(this);
btn2.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.button1:
Toast.makeText(getApplicationContext(), "Loading Gridview 1", Toast.LENGTH_LONG).show();
intent = new Intent(MainActivity.this, GridViewActivity.class);
intent.putExtra("folder", "folder1");
startActivity(intent);
break;
case R.id.button2:
Toast.makeText(getApplicationContext(), "Loading Gridview 2", Toast.LENGTH_LONG).show();
intent = new Intent(MainActivity.this, GridViewActivity.class);
intent.putExtra("folder", "folder2");
startActivity(intent);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
So in this activity am passing different folder names for each button clicks.
GridViewActivity.java
This class will receive the intent parameters for the folder names and it will list all image thumbnails for that specific folder. Until here everything is fine and I can view the images for each different folder depending on the button clicked.

Now Once I click on an image thumbnail my (FullScreenView Activity) cannot pickup the folder names so I can display the Image in Fullscreen mode.

setContentView(R.layout.activity_fullscreen_view);
viewPager = (ViewPager) findViewById(R.id.pager);
//utils = new GridViewActivity(getApplicationContext());
Intent i = getIntent();
int position = i.getIntExtra("position", 0);
adapter = new FullScreenImageAdapter(FullScreenViewActivity.this,
gv.getFilePaths());
viewPager.setAdapter(adapter);
// displaying selected image first
viewPager.setCurrentItem(position);
}
}
I want to know how can I receive the file parameters in my FullScreenActivity?
You can use
intent.putStringArrayListExtra("paths", getFilePaths());
when you go from GridViewActivity to FullScreenViewActivity and in onCreate of FullScreenViewActivity you can do
ArrayList<String> paths = getIntent().getStringArrayListExtra("paths");
which will give you the paths of the images
I've created a file manager that I will use in my other program, however I am having problems with it. It displays a list of files on my android phone, and I can click through one folder deep, however going more than one it stops working. Mainly I think because of "if(K.getAbsoluteFile().isDirectory()==true)", if I get rid of this line though it simply crashes. So it seems to only allow me to go one folder deep, can anyone figure out what I've done wrong here?
Also any guides or what have you on this topic would be appreciated, its kind of a mangling of random code I've found.

Im starting to work with Honeycomb, and im trying to make a simple fragmented layout with the list of file on the left side, and the details of the file on the right (when a file is selected). Well, it was going well until I actually tried to list the files, and now I just get a "/" slash, and thats it. Nothing else. I set up a log to track the number of files in the directory im in, and it sees 26, but it wont list them. Heres my code

So, it runs, I got my fragments to layout,but it wont list the files. Any help would be appreciated. Oh, when I try to put in a for loop to add each name of the files to my log, it gives a nullpoint exception
Edit: I think I have chased it down to the resource file for the Row that its actually using, which is R.layout.row, but I dont see whats wrong. Heres the layout for that file
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="40sp"
android:padding="5dip"
android:background="#color/white"
android:gravity="center_vertical"/>
Add the follow after the call to
//Browse to root directory
browseTo(new File("/"));
ListView lv = getListView();
lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
lv.setCacheColorHint(Color.TRANSPARENT);
