从android应用中的摄像头捕获图像后，单击onActivityResult（）中的按钮

Question

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // Check which request we're responding to
    if (requestCode == PICK_CONTACT_REQUEST) {
        // Make sure the request was successful
        if (resultCode == RESULT_OK) {
            //Button Click
        }
    }
}

Here if the RESULT_OK,how to click a button and do whatever we want. Please Help me to find the solution.I have used if(getTaskId()==R.id.PassImageBtn){} but nothing is happening if I click on the Button.

Answer 1

Use performClick () method to the call button click event.

private Button mButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.my_layout);
    mButton = findViewById(R.id.my_button);
    mButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // ...
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // Check which request we're responding to
    if (requestCode == PICK_CONTACT_REQUEST) {
        // Make sure the request was successful
        if (resultCode == RESULT_OK) {
            mButton.performClick();
        }
    }
}
