Activity related to Android Jump
Within the module normal jump
Explicit Jump
Intent intent = new Intent();
intent.setClass(this, xxxrActivity.class);
intent.putExtra("key","value");
startActivity(intent);
Jump between module
Implicit Jump
1: The specific activity jump path
Intent intent = new Intent();
intent.setClassName(getPackageName(), "com.xxx_xxxActivity");
intent.putExtra("key", "value");
if (getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY)!= null){
startActivity(intent);
}else {
Toast.makeText(this,"找不到你想要的activity",Toast.LENGTH_SHORT).show();
}
2: The configuration of a jump action activity
//配置action
<activity android:name="com.xxx.xxxActivity" >
<intent-filter>
<action android:name="xxx" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Intent intent = new Intent();
intent.setPackage(getPackageName());//配置包名,防止提醒进那个同样action的activity
intent.setAction("x'x'x");//配置的action
intent.putExtra("key", "value");
if (getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY)!= null){
startActivity(intent);
}else {
Toast.makeText(this,"找不到你想要的activity",Toast.LENGTH_SHORT).show();
}
Implicit Jump security
Note: If you remove Activity location module, without removing Jump, Activity will collapse phenomenon.
So, call resolveActivity () to do judgment empty.
if (getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY)!= null){
startActivity(intent);
}else {
Toast.makeText(this,"找不到你想要的activity",Toast.LENGTH_SHORT).show();
}
