Android(安卓)从一个App跳转到另一个App

我们从一个App需要跳转到另一个App的话,我们要知道这个App

的包名,然后直接调用这个封装好的方法,将包名穿进去就可以,

废话不多说,贴代码:

private void openApp(String packageName) {        PackageInfo pi = null;        try {            pi = MainActivity.this.getPackageManager().getPackageInfo(packageName, 0);        } catch (PackageManager.NameNotFoundException e) {            e.printStackTrace();        }        Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);        resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);        resolveIntent.setPackage(pi.packageName);        List apps = MainActivity.this.getPackageManager().queryIntentActivities(resolveIntent, 0);        ResolveInfo ri = apps.iterator().next();        if (ri != null ) {            packageName = ri.activityInfo.packageName;            String className = ri.activityInfo.name;            Intent intent = new Intent(Intent.ACTION_MAIN);            intent.addCategory(Intent.CATEGORY_LAUNCHER);            ComponentName cn = new ComponentName(packageName, className);            intent.setComponent(cn);            startActivity(intent);        }    }

好了,到这里就已经完成了
