Question

小弟今日学习Android，在把书上的例子抄进eclipse的运行的时候发现跳出这个错误，请问有没有人也碰到过呢：

Answer 1

请贴代码，可能是你重复的添加某个对象，导致了memory leak发生太频繁了。

Answer 2

代码是：
public class Sudoku extends Activity implements OnClickListener {

private static final String TAG = "Suduku";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        //set up click listeners for all the buttons
        View continueButton = this.findViewById(R.id.continue_button);
        continueButton.setOnClickListener(this);
        View newButton = this.findViewById(R.id.new_button);
        newButton.setOnClickListener(this);
        View aboutButton = this.findViewById(R.id.about_button);
        aboutButton.setOnClickListener(this);
        View exitButton = this.findViewById(R.id.exit_button);
        exitButton.setOnClickListener(this);
    }
    
    /** Called when click screen. */
public void onClick(View v) {
switch (v.getId()) {
case R.id.about_button:
Intent i = new Intent(this, About.class);
startActivity(i);
break;
case R.id.new_button:
openNewGameDialog();
case R.id.exit_button:
finish();
break;
}
}

    /** Called when menu created. */
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
     super.onCreateOptionsMenu(menu);
     MenuInflater inflater = getMenuInflater();
     inflater.inflate(R.menu.menu, menu);
     return true;
    }
    
    /** Called when menu click. */
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
     switch (item.getItemId()) {
     case R.id.settings:
     startActivity(new Intent(this, Settings.class));
     break;
     }
     return false;
    }
    
    /** open the game level to be select. */
    private void openNewGameDialog() {
     Log.d(TAG, "Show the select Dialog...");
     new AlertDialog.Builder(this)
     .setTitle(R.string.new_game_title)
     .setItems(R.array.difficuty, 
     new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialoginterface, int i) {
     startGame(i);
     }
     })
     .show();
    }
    
    /** start the game. */
    private void startGame(int i) {
     Log.d(TAG, "Clicked on " + i);
    }
}多选项用配置array.xml：<?xml version="1.0" encoding="utf-8"?>
<resources>
<array name="difficuty">
<item>@string/easy_label</item>
<item>@string/medium_label</item>
<item>@string/hard_label</item>
</array>
</resources>值配置strings.xml        <string name="new_game_title">Difficulty</string>
<string name="easy_label">Easy</string>
<string name="medium_label">Medium</string>
<string name="hard_label">Hard</string>

Answer 3

问题不在于添加太频繁了
而在于变态的1.6（2.2没有这个问题）怎么弹出对话框
因为activity在弹出对话框之前要调用onpause方法，而这个方法之后再show dialog就会leak
有谁知道1.6怎么让activity弹出对话框吗？别说在onpause里关闭对话框，我就是需要这个对话框

Answer 4

在没有关闭对话框的时候你把activity给finish，所以造成了这样的结果

Answer 5

我也遇到这个问题了，把hide方法换成dismiss之后就没有问题了。不知道你们的行不。

Answer 6

楼上说的没错，case语句有问题，少个break。android的dialog创建的时候会传入一个参数this，就是你当前的activity，你的dialog必须在Activity销毁之前先释放掉，否则就会报windowleaked的错误。http://407827531.iteye.com/blog/1021603 这篇里面有讲到
