Android Tips - Using Layout Param

Layout Param is used to change the layout properties. You can create a layout instance and assign to required view.

LinearLayout.LayoutParams layoutParam = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

Sample Code

LinearLayout.LayoutParams mLayoutParam = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
Button mButton = new Button(this);
mButton.setLayoutParams(layoutParam);

The above code works fine but this is not a current solution. It should like the below code

Button mButton = new Button(this);
ViewGroup.LayoutParam mLayoutParam= mButton.getLayoutParams();
mLayoutParam.height = ViewGroup.LayoutParams.FILL_PARENT


Thanks to Ashok , I have done the mistake and corrected me

Android Window Leak

The WindowLeaked exception in the log usually happens when you have some sort of async task that is finishing after the activity that began it is destroyed.
Solution for the above issue, we can dismiss the progress dialog before finish the activity.


Issue :

Activity com.sample.ViewLeakIssueActivity has leaked window com.android.internal.policy.impl.TvWindow$DecorView@6bc30788 that was originally added here
E/WindowManager( 1687): at android.view.ViewRoot.(ViewRoot.java:230)
E/WindowManager( 1687): at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:148)
-----

Sample Leak Issue
public class ViewLeakIssueActivity extends Activity {
volatile ProgressDialog pd;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
pd = ProgressDialog.show(ViewLeakIssueActivity.this, "", "test...", true);

new Thread() {
public void run() {
try {
sleep(5000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("@@@@@@@@@@@"+ViewLeakIssueActivity.this+pd.isShowing());

pd.dismiss();
}
}.start();

finish();

}

}

Solution for the above issue, we can dismiss the progress dialog before finish the activity.

@Override
public void finish() {
if(pd.isShowing()){
pd.dismiss();
}
super.finish();
}
