透明活动与背景活动在Android中的点击行为 [英] Transparent Activity with background activity click through behaviour in android

问题描述

您好stackoverflow我正在尝试开发具有基本活动和Transparent活动的应用程序，到目前为止，我已经能够使用以下代码在基本活动之上创建Activity和Transparent活动

Hi stackoverflow I'm trying to develop an application with a base activity and a Transparent activity, so far I'm able to create a Activity and a Transparent activity over base activity using follwing code

MainActivity.java

public class MainActivity extends Activity {

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

    startActivity(new Intent(this, TransparentActivity.class));

    findViewById(R.id.button2).setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(MainActivity.this, "Main", Toast.LENGTH_SHORT).show();

        }
    });
}
}

TransparentActivity.java

public class TransparentActivity extends Activity {

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

    findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(TransparentActivity.this, "Btn1", Toast.LENGTH_SHORT).show();
        }
    });
}
}

styles.xml

<resources>
<style name="Theme.Transparent" parent="android:Theme">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>
</style>

Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

<application
    android:allowBackup="true"

    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

        android:label="@string/app_name" >

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.example.test.TransparentActivity"
        android:theme="@style/Theme.Transparent" >
    </activity>
</application>

</manifest>

activity_main.xml

<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/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/textView1"
    android:layout_marginLeft="52dp"
    android:layout_toRightOf="@+id/textView1"
    android:text="Button" />

</RelativeLayout>

activity_transparent.xml

<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" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_marginBottom="29dp"
    android:layout_marginRight="44dp"
    android:text="Button" />

</RelativeLayout>

但是我希望Base Activity与TransparentActivity一样也可触摸.请有人帮我解决这个奇怪的谜语. 谢谢.

But I want the Base Activity to be touchable as well along with TransparentActivity. Please some one help me to solve this strange riddle. Thanks.

推荐答案

在super.onCreate()方法上方的透明活动"中添加这些行.

Add these lines in the Transparent Activity above super.onCreate() method.

getWindow().setFlags(LayoutParams.FLAG_NOT_TOUCH_MODAL,
            LayoutParams.FLAG_NOT_TOUCH_MODAL);

    // ...but notify us that it happened.
getWindow().setFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
            LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);

像这样的透明布局.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="8dp" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="29dp"
    android:layout_marginRight="44dp"
    android:text="Button" />
