java - 如果我有带有包含按钮的自己的单击事件的 LinearLayout，我如何单击按钮

Question

 <LinearLayout
    android:id="@+id/btn1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_vertical" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/btn_image" />

    <TextView
        android:layout_width="150dp"
        android:layout_height="fill_parent"
        android:gravity="center_vertical"
        android:text="something" />

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>


btn1 = (LinearLayout) findViewById(R.id.btn1);
btn1.setOnClickListener(this);
btn = (Button) findViewById(R.id.btn);
btn.setOnClickListener(this);

我无法点击按钮。总是称为单击 LinearLayout。

@Override
public void onClick(View v) {

    switch (v.getId()) {
    case R.id.btn:
// set something parametr
        break;
    case R.id.btn1:
// go to activity
        break;
    }   

}

似乎像这样为我工作，

你的xml文件，

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

 <LinearLayout
    android:id="@+id/btn1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_vertical" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:layout_width="150dp"
        android:layout_height="fill_parent"
        android:gravity="center_vertical"
        android:text="something" />

    <Button
        android:id="@+id/btn"
        android:text="Button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

</RelativeLayout>

还有你的活动课，

public class MainActivity extends Activity implements OnClickListener{
     LinearLayout  btn1 =null;
     Button     btn =null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
           btn1 = (LinearLayout) findViewById(R.id.btn1);
           btn1.setOnClickListener(this);
           btn = (Button) findViewById(R.id.btn);
           btn.setOnClickListener(this);
    }

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

    public void onClick(View v) {

        if(v==btn)
        {
            Toast.makeText(getApplicationContext(), "btn clicked", Toast.LENGTH_SHORT).show();
        }

        if(v==btn1)
        {
            Toast.makeText(getApplicationContext(), "btn1 clicked", Toast.LENGTH_SHORT).show();
        }
    }


}

在标签中放置可点击的 true ..

文件android:clickable="true"

  <LinearLayout
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical" android:onClick="" >

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/actionbar_background" />

        <TextView
            android:layout_width="150dp"
            android:layout_height="fill_parent"
            android:gravity="center_vertical"
            android:text="something" />

        <Button
            android:id="@+id/btn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true" />

    </LinearLayout>

...................................................

btn1 = (LinearLayout) findViewById(R.id.btn1);

btn1.setOnClickListener(this);

btn = (Button) findViewById(R.id.btn);

btn.setOnClickListener(this);

...................................................

   @Override
   public void onClick(View v) {

      switch (v.getId()) {
      case R.id.btn:
         // set something parametr
       break;
     case R.id.btn1:
         // go to activity
       break;
    }   

   }

Answer 3

您仍然可以在 onclick 方法中进行区分：

@Override
public void onClick(View v) {

    if (v.getId() == R.id.btn1)
    {
        // Linear was clicked
    }
    else if (v.getId() == R.id.btn){
        // Button was clicked
    }

}

但是您仍然应该从线性中删除按钮
