Try to dynamically create the ImaveView. The snippet code is listed
below. It's not the solution just a hint. For testing you can call
also System.gc() after setContentView(new View(this)); But using it in
your code is not a good way. Read this
http://blog.javia.org/android-allocation-free-code-avoids-the-gc-freeze/
@Override
protected void onStart() {
super.onStart();
Log.v(TAG, "onStart");
setContentView(R.layout.main);
ImageView iv = new ImageView(this);
iv.setBackgroundResource(R.drawable.forest);
iv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
startActivity(new Intent(FirstActivity.this,
SecondActivity.class));
}
});
LinearLayout ll = (LinearLayout)findViewById(R.id.first_ll);
ll.addView(iv);
}
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/first_ll"
xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:id="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</EditText>
</LinearLayout>
