Android LinearLayout整个布局设置不可点击

Posted 2021-12-30 ly570

1，activity的xml布局（布局中有个Button按钮，点击按钮弹出一个popupwindow ）

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:background="@drawable/ic_launcher_background"
tools:context=".MainActivity">

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:onClick="click"
android:textSize="30sp"
android:text="弹窗Popupwindow"/>

</LinearLayout>
2，上图中有白色背景的popupwindow 的xml布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:id="@+id/ll_popup">

<LinearLayout
android:id="@+id/ll_popup_content"
android:layout_width="600dp"
android:layout_height="400dp"
android:gravity="center"
android:background="@android:color/white">
<ImageView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="250dp"
android:padding="10dp"
android:src="@drawable/fengjing"
android:layout_marginRight="20dp"/>
<ImageView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="250dp"
android:padding="10dp"
android:src="@drawable/small"/>
</LinearLayout>

</LinearLayout>
3，MainActivity的代码实现：

public class MainActivity extends AppCompatActivity
private View pop;

private LinearLayout ll_popup,ll_popup_content;

@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

pop = View.inflate(this, R.layout.popupwindow_test, null);
ll_popup = pop.findViewById(R.id.ll_popup);
ll_popup_content = pop.findViewById(R.id.ll_popup_content);
ll_popup_content.setOnClickListener(null);//Linearloyout就不可点击了


public void click(View view)
final PopupWindow popupWindow = new PopupWindow(pop, MATCH_PARENT, MATCH_PARENT);
ll_popup.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
popupWindow.dismiss();

);
popupWindow.showAtLocation(getWindow().getDecorView(), Gravity.TOP,0,0);





@Override
public void onWindowFocusChanged(boolean hasFocus)
//完全沉浸式
super.onWindowFocusChanged(hasFocus);
if (hasFocus && Build.VERSION.SDK_INT >= 19)
View decorView = getWindow().getDecorView(http://www.my516.com);
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
