1、背景
- A应用 通过 startActivityForResult 启动 B 应用，同时 B 应用 通过 setResult 进行数据回传。注意：这里B应用模拟了在第一个页面和第二页面返回的情况
2、A应用
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onJumpBApplication(View view){
String schema = "myapplication://test?redirectUrl=xxxxx"
Intent intent = new Intent("test.android.example" , Uri.parse(schema));
intent.putExtra("value" , "调用成功" );
startActivityForResult(intent, 1001 );
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
if (requestCode == 1001){
if (resultCode == RESULT_OK){
if (data != null){
String code = data.getStringExtra("code");
tvResult.setText(code);
}
}
}
super.onActivityResult(requestCode, resultCode, data);
}
}
2、B应用
