How can I get ID from ViewBinding to use it with switch case statement?-CodePudding

@Override
public void onClick(View v) {
    switch (v.getId()){
        case R.id.iv_camera:
            Toast.makeText(this, "Camera Clicked", Toast.LENGTH_SHORT).show();
            break;
        case mBinding.ivCamera.getId():
            break;
    }
}

The first case works perfectly fine however, the second one throws an error that says Constant Expression Required . Am i forced to use R.id.something or can I continue with view binding?

CodePudding user response：

The reason is that case statements in java needs to be compile time constant. Since mBinding.ivCamera.getId() is not thus the error. Here is already an answer in detail.
