我有来自另一个ListActivity的ListActivity Intent，大约1倍到10倍的程序崩溃Intent活动，当我记录问题是setContentView行

public class MessageActivity extends ListActivity {
 private ListView list;

 //...

  @Override
  public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_message);
     list = getListView();

  //...

  }
}

activity_message XML：

使用ListActivity时不应使用setContentView 如果你需要，你应该使用Activity并在其布局中使用ListView小部件

public class MainActivity extends Activity {
private Context A;
private ListView list;
private LazyAdapter adapter;
private LinearLayout search_layer;
...

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
    setContentView(R.layout.activity_main);
    this.A = this;
    list = (ListView) findViewById(R.id.listView);
    adapter = new LazyAdapter(this, R.layout.list_row, R.layout.layout_one, H.BoxInfo);
    setListAdapter(adapter);

    ...
    Button search_button = (Button) A.findViewById(R.id.activity_main_button_search);
    search_layer = (LinearLayout) A.findViewById(R.id.activity_main_search_layer);
    search_layer.setVisibility(View.GONE);
    search_button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Vibrator vibe = (Vibrator) A.getSystemService(Context.VIBRATOR_SERVICE);
            vibe.vibrate(50);
            if (search_layer.getVisibility() == View.GONE) {
                search_layer.setVisibility(View.VISIBLE);
                search_text.requestFocus();

            } else {
                search_layer.setVisibility(View.GONE);
                search_text.setText("");
                imm.hideSoftInputFromWindow(search_text.getWindowToken(), 0);
            }
        }
    });


    list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        public boolean onItemLongClick(AdapterView parent, View view, int position, long id) {
            Vibrator vibe = (Vibrator) A.getSystemService(Context.VIBRATOR_SERVICE);
            vibe.vibrate(50);
            BoxInfoObject Box = adapter.getItem(position);
            inbox_init QA = new inbox_init(A, adapter, Box);
            inboxQuickAction quickAction = QA.initialize(Box);
            quickAction.show(view);
            return true;
        }
    });

    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> a, View v, int position, long id) {
            BoxInfoObject Box = adapter.getItem(position);
            Intent intent = new Intent(A, MessageActivity.class);
            intent.putExtra(MessageActivity.KEY_POSITION, H.BoxInfo.indexOf(Box) + "");
            intent.putStringArrayListExtra(MessageActivity.KEY_NEW_MESSAGE_OPNS,
                    Box.getOPNs());
            intent.putStringArrayListExtra(MessageActivity.KEY_NEW_MESSAGE_PNS,
                    Box.getPNs());
            A.startActivity(intent);
        }
    });

} catch (Exception e3) {
    Log.i("H", "MainActivity.Exception e3******************************");
    Toast.makeText(this, this.getString(R.string.error1) +
            "002" + this.getString(R.string.error2)
            , Toast.LENGTH_LONG).show();
    onBackPressed();
}
}


@Override
public void onBackPressed() {
if (search_layer.getVisibility() == View.VISIBLE) {
    search_layer.setVisibility(View.GONE);
} else {
Intent i = new Intent(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);
startActivity(i);
}
}

@Override
public void onPause() {
Log.i("H", "MainActivity.onResume");
super.onPause();
}

@Override
protected void onResume() {
Log.i("H", "MainActivity.onResume");
super.onResume();
}

@Override
protected void onRestart() {
super.onRestart();
Log.i("H", "MainActivity.onRestart");
}

@Override
protected void onStart() {
super.onStart();
Log.i("H", "MainActivity.onStart");
}

@Override
protected void onStop() {
super.onStop();
Log.i("H", "MainActivity.onStop");
}

@Override
public void onDestroy() {
Log.i("H", "MainActivity.onResume");
super.onDestroy();
}
}

答案 1 :(得分：0)

您的代码未达到search_layer = (LinearLayout) A.findViewById(R.id.activity_main_search_layer);所以在onBackPressed()中，search_layer为空，这就是您获得NullPointerException的原因，您需要弄清楚为什么会抛出e3。 因为你有OutOfMemoryException，我猜你正在使用的图像非常大。尝试减小它们的大小，看看它是否再次发生。如果可以的话，也可以尝试避免使用过多的透支。
