Android“应用程序意外停止。请再试一次。”

我正在为我的工作制作Android应用。应用程序开发过程相当新，所以我在开发的早期阶段测试它。

这是日食代码：

public class ClientFeedbackActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setContentView(R.Layout.main);

    ImageButton mPortrait = (ImageButton)findViewById(R.id.imgPortrait);
    mPortrait.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getBaseContext(),
                    "You have clicked the Portrait button", 
                    Toast.LENGTH_SHORT).show();         
        }
    });

    EditText mComments = (EditText)findViewById(R.id.txtComments);
    mComments.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            return false;
        }
    });

    Button mSave = (Button)findViewById(R.id.btnSave);
    mSave.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getBaseContext(), 
                    "You have clicked the Save button", 
                    Toast.LENGTH_SHORT).show();
        }
    });


    Button mClear = (Button)findViewById(R.id.btnClear);
    mClear.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getBaseContext(),
                    "You have clicked on the Clear button",
                    Toast.LENGTH_SHORT).show();
        }
    });

    setContentView(R.layout.main);
}
}

我的布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/RLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"

<TextView

    />
<Button

    android:text="Clear"
    android:layout_toRightOf="@+id/btnSave"
    android:layout_alignParentBottom="true"
    />
</RelativeLayout>

我的宣言：

    </activity>

</application>

最后，我的logcat：

对帖子的长度表示道歉，但我没有第一个线索，为什么这不起作用。 任何帮助将不胜感激。

6 个答案:

答案 0 :(得分：1)

您必须设置内容视图...否则将如何检索该布局？并且还以更好的方式处理异常处理......

答案 1 :(得分：0)

您应首先在setContentView()中调用onCreate()方法注册您的布局，然后调用findViewById()方法。

答案 2 :(得分：0)

 super.onCreate(savedInstanceState);

this.setContentView(R.layout.your_layout)

答案 3 :(得分：0)

您只是不设置内容，在ImageButton之前需要setContentView(R.layout.your_lauyout)。

答案 4 :(得分：0)

正如其他朋友所说，你将方法setContentView（R.layout.xxxxx）添加到你的项目中。我想说的一件重要的事情是，在可疑方法周围放置try-catch块。这可能有助于您跟踪异常（如果有）。

答案 5 :(得分：0)

您正在调用两次 setContentView（R.layout.main）; 此方法。

plz 删除setContentView（R.layout.main）;从底部。
