Question

当我运行我的应用程序时，这只是一个通过按下按钮调用另一个应用程序的活动，我得到了这个例外。

虽然我的xml中没有这样的视图，但有关于imageview的例外情况。

以下是例外：

这是我的代码：

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {

    Button b_button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b_button = (Button) findViewById(R.id.b_button1);
        b_button.setOnClickListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.b_button1:
            Intent intentToFirstActivity = new Intent(MainActivity.this,
                    FirstAcitivty.class);
            startActivity(intentToFirstActivity);
            break;
        default:
            break;
        }
    }
}

我的xml布局是：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <Button
        android:id="@+id/b_button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="133dp"
        android:layout_toRightOf="@+id/textView1"
        android:text="Button" />

</RelativeLayout>

您的问题似乎没有任何问题。我建议你只清理一次项目并生成让它生成R.java文件。

我运行应用程序时出现未知异常
