打开文件选择器
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType( "*/*" );
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult( Intent.createChooser(intent, "Select a File to Upload" ), FILE_SELECT_CODE);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText( this , "Please install a File Manager." , Toast.LENGTH_SHORT).show();
}
} |
选择的结果
@Override protected void onActivityResult( int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case FILE_SELECT_CODE:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri uri = data.getData();
String path = FileUtils.getPath( this , uri);
}
break ;
}
super .onActivityResult(requestCode, resultCode, data);
} |
FileUtils文件
public class FileUtils {
public static String getPath(Context context, Uri uri) {
if ( "content" .equalsIgnoreCase(uri.getScheme())) {
String[] projection = { "_data" };
Cursor cursor = null ;
try {
cursor = context.getContentResolver().query(uri, projection, null , null , null );
int column_index = cursor.getColumnIndexOrThrow( "_data" );
if (cursor.moveToFirst()) {
return cursor.getString(column_index);
}
} catch (Exception e) {
// Eat it
}
}
else if ( "file" .equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null ;
}
} |
这个很简单。
