java - 如何更改或设置新的 Activity 启动器应用程序？ ( java 语)

Question

我有一个付款 Activity 和启动 Activity ，它在用户购买后显示内容应用程序。付款 Activity 是Manifest.xml中的默认启动器，我想将启动器 Activity 设置为启动 Activity ，并在付款后禁用付款 Activity 。

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.exa.iu2">

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

    <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/AppTheme">
        <activity android:name=".PaymentActivity" android:theme="@style/SplashTheme">

            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <action android:name="android.intent.action.VIEW"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.VIEW"/>
                <category android:name="android.intent.category.DEFAULT"/>
                <category android:name="android.intent.category.BROWSABLE"/>
                <data android:scheme="return" android:host=“zrp”/>
            </intent-filter>
        </activity>
            <activity-alias
                android:name=".PaymentActivity"
                android:icon="@mipmap/ic_launcher"
                android:label="@string/app_name"
                android:roundIcon="@mipmap/ic_launcher_round"
                android:enabled="false"                              android:targetActivity=".SplashActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <action android:name="android.intent.action.VIEW"/>
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>
        <activity
                android:name=".MainActivity"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@style/AppTheme.NoActionBar"/>
    </application>
</manifest>

在付款 Activity 和“如果付款成功”

public void onCallbackResultVerificationPayment(boolean isPaymentSuccess, String refID, PaymentRequest paymentRequest) {
        if(isPaymentSuccess){
            Toast.makeText(PaymentActivity.this, “Payment Success” + refID, Toast.LENGTH_SHORT).show();
            ComponentName cm = new ComponentName("com.exa.iu2", "com.exa.iu2"+".SplashActivity");
            ComponentName cm2 = new ComponentName("com.exa.iu2", "com.exa.iu2"+".PaymentActivity");
            PackageManager pm = getApplication().getPackageManager();
            pm.setComponentEnabledSetting(cm, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);
            pm.setComponentEnabledSetting(cm2, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,0);
        }else {
            Toast.makeText(PaymentActivity.this, “Don’t success”, Toast.LENGTH_SHORT).show();
        }
        }
    });

谢谢

我建议您创建一个中心或启动 Activity 来决定要显示的内容。显然，新 Activity 必须设置为 Main -> Launcher Activity 。
