Question

在MainActivity上的

我有几个按钮，我希望每个按钮都转到另一个xml页面。我有一个按钮的代码到一个页面正常工作。但我无法通过代码解决这个问题的解决方案。

@Override
protected void onCreate(Bundle savedInstanceStae){
    super.onCreate(savedInstancesState);
    setContentView(R.layout.activity_index);

    Button button1 = (Button)findViewById(R.id.button1);
    button1.setOnClickListener(new OnClickListener(){

    public void onClick(View v){

    Intent intent = new Intent(v.getContext(), voorbeeld.class);
    startActivityForResult(intent, 0);
    }
  });
 }

//This is only for one button, has somebody a solution to work with several buttons

使用onclicklistener实现您的活动，并编写类似下面的代码

public class MainActiv1ity extends Activity implements View.OnClickListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
       Button button1 = (Button)findViewById(R.id.button1);
       Button button2 = (Button)findViewById(R.id.button2);
       Button button3 = (Button)findViewById(R.id.button3);
       Button button4 = (Button)findViewById(R.id.button4);
       button1.setOnClickListener(this);
       button2.setOnClickListener(this);
       button3.setOnClickListener(this);
       button4.setOnClickListener(this);
}
@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.button1:
        //do your logic
        break;
    case R.id.button2:
        //do your logic
        break;
    case R.id.button3:
        //do your logic
        break;
    case R.id.button4:
        //do your logic
        break;
    default:
        break;
    }
}

}

在每个按钮的XML中，添加一个新的android:onClick="methodName"，每个按钮使用不同的methodName。

然后在您的活动类中，添加具有该名称的方法，该方法将视图作为参数并为每个创建新的意图：

public void methodName2(View view) {
    Intent intent = new Intent(v.getContext(), activityForButton1.class);
    startActivity(intent);
}
public void methodName2(View view) {
    Intent intent = new Intent(v.getContext(), activityForButton2.class);
    startActivity(intent);
}
public void methodName2(View view) {
    Intent intent = new Intent(v.getContext(), activityForButton3.class);
    startActivity(intent);
}

按钮活动到另一页面
