嗨,我正在做網格視圖的簡單演示。我有關於改變佈局的問題。如果我們改變方向模式,它重置GridVIew。
當我的演示在ladscape模式下工作時,它存儲複選框的值。但是當我改變方向到任何模式。它再次調用onCreate()方法並重置所有值。可以anybdy建議我。在方向發生變化後如何保留值。
這裏是我的代碼:
btnSubmit = (Button) findViewById(R.id.editButton);
btnSubmit.setOnClickListener(this);
gridview.setAdapter(new ImageAdapter(this, status));
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
ImageView imgview = (ImageView) v.findViewById(R.id.imgvew);
imgview.setImageResource(R.drawable.check_box_checked);
}
});
@Override
public void onConfigurationChanged(android.content.res.Configuration newConfig) {
if (newConfig.ORIENTATION_LANDSCAPE == Configuration.ORIENTATION_PORTRAIT){
}
};
@Override
public void onClick(View v) {
status = true;
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this, status));
}

Put super.onResume();到您的overres的onResume方法結束 – 2012-03-07 17:23:17
