我的Android應用程序有問題。我想通過這樣做,創建一個新的觀點:關於繼承視圖的setLayoutParams
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
LinearLayout l = (LinearLayout)findViewById(R.id.mainActivity);
f = new InheritedView(this);
f.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
l.addView(f);
}
隨着
public class InheritedView extends ImageView implements AbstractView
public InheritedView(Context context) {
super(context);
}
但是,當我測試,執行setLayoutParams當我的應用程序崩潰與java.lang.StackOverflowError的(..)。 但是,下面的工作:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
LinearLayout l = (LinearLayout)findViewById(R.id.mainActivity);
f = new ImageView(this);
f.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
l.addView(f);
}
logcat的文件

您是否嘗試切換addView和setLayoutParams行? – Blackbelt
我有。它崩潰,因爲缺乏必要的參數,我猜... –
有一些東西在logcat中出現。應用程序不會無緣無故地崩潰。 –
