1.调用支付宝扫一扫界面：
Uri uri = Uri.parse("alipayqr://platformapi/startapp?saId=10000007");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
2.调用支付宝收款码界面：
Uri uri = Uri.parse("alipayqr://platformapi/startapp?saId=20000056");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
3.调用微信扫一扫界面：
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.tencent.mm", "com.tencent.mm.ui.LauncherUI"));
intent.putExtra("LauncherUI.From.Scaner.Shortcut", true);
intent.setFlags(335544320);
intent.setAction("android.intent.action.VIEW");
startActivity(intent);
4.调用微信收款码，这里需要使用辅助功能实现
1.在AndroidMainfest.xml中注册辅助功能
<service
android:name=".PayAccessibility"
android:enabled="true"
android:exported="true"
android:foregroundServiceType="location"
android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
<intent-filter>
<action android:name="android.accessibilityservice.AccessibilityService" />
</intent-filter>
<meta-data
android:name="android.accessibilityservice"
android:resource="@xml/pay_accessibility_config" />
</service>
2.在res下的xml配置服务config， 即pay_accessibility_config
<?xml version="1.0" encoding="utf-8"?>
<accessibility-service
xmlns:android="http://schemas.android.com/apk/res/android"
android:accessibilityEventTypes="typeWindowStateChanged|typeViewFocused|typeViewClicked"
android:accessibilityFeedbackType="feedbackGeneric"
android:accessibilityFlags="flagDefault"
android:canRetrieveWindowContent="true"
android:canRequestFilterKeyEvents ="true"
android:notificationTimeout="100"
android:packageNames="@null"
android:description="@string/accessibility_description"/>
3.辅助功能具体实现
package com.sanyesan.paymodel;

import android.content.Intent;

public class PayAccessibility extends AccessibilityService {

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
int eventType = event.getEventType();
Log.d(TAG, "onAccessibilityEvent: 活动事件"+event.getEventType());
switch (eventType){

this.intent = intent;
isPaymentReceivedClick = false;//重置

}
最后，启动辅助功能并调用微信付款码
if(isAccessibilitySettingsOn(MainActivity2.this)){
Intent intent = new Intent(MainActivity2.this, PayAccessibility.class);
startService(intent);
new Handler(Looper.getMainLooper()).postDelayed(() -> {
Intent intent1 = new Intent();
ComponentName cmp = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.LauncherUI");
intent1.setAction(Intent.ACTION_MAIN);
intent1.addCategory(Intent.CATEGORY_LAUNCHER);
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent1.setComponent(cmp);
startActivity(intent1);
}, 200);
}else {
startActivity(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS));
finish();
}
注意：必须得增加辅助功能权限的判断
/**
* 辅助服务是否开启
*
* @param context 活动context
* @return
*/
public static boolean isAccessibilitySettingsOn(Context context) {
int accessibilityEnabled = 0;
final String service = context.getPackageName() + "/" + PayAccessibility.class.getCanonicalName();
try {
accessibilityEnabled = Settings.Secure.getInt(context.getApplicationContext().getContentResolver(),
Settings.Secure.ACCESSIBILITY_ENABLED);
} catch (Settings.SettingNotFoundException e) {
e.printStackTrace();
}
TextUtils.SimpleStringSplitter mStringColonSplitter = new TextUtils.SimpleStringSplitter(':');
if (accessibilityEnabled == 1) {
String settingValue = Settings.Secure.getString(context.getApplicationContext().getContentResolver(),
Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);
if (settingValue != null) {
mStringColonSplitter.setString(settingValue);
while (mStringColonSplitter.hasNext()) {
String accessibilityService = mStringColonSplitter.next();
if (accessibilityService.equalsIgnoreCase(service)) {
return true;
}
}
}
}
return false;
}
