致命异常：java.lang.IllegalStateException：无法执行 android:onClick 的方法

Question

我在 logcat 中收到这些错误：

FATAL EXCEPTION: main  Process: com.sreekanth.gifapp, PID: 14761
java.lang.IllegalStateException: Could not execute method for android:onClick

我尝试更改方法的名称，但没有成功。这是我的代码：

XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

Activity:

public class MainActivity extends Activity {

      private   final  int VIDEO_REQUEST_CODE =100;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }

        public void vMethod (View view) {
            Intent camera_intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
            File video_fileq = getFilepath();
            Uri video_uri = Uri.fromFile(video_fileq);
            camera_intent.putExtra(MediaStore.EXTRA_OUTPUT,video_uri);
            Intent intent = camera_intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
            startActivityForResult(camera_intent,VIDEO_REQUEST_CODE);
        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {

            if(requestCode == VIDEO_REQUEST_CODE) {
                if(requestCode == RESULT_OK) {
                    Toast.makeText(getApplicationContext(),"video captured successufully",Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getApplicationContext(),"video capture failed...",Toast.LENGTH_SHORT).show();
                }
            }
        }

        public File getFilepath() {
            File folder = new File("sdcard/video_captured");

            if (!folder.exists()) {
                folder.mkdir();
            }

            File video_file = new File(folder,"sample_video.mp4");
            return video_file;
        }
    }

这是完整的 logcat app.Please 遍历我的 logcat provided.These 是我 facing.I 试图解决的错误改了方法名，还是不行

Answer 1

为什么不尝试另一种方式...

声明一个按钮对象：

Button button_gif;

在 onCreate

中从 xml 获取按钮资源

 button_gif = (Button) findViewById(R.id.btngif);

并在 Activity 中实现 onClickListener 接口，因此您必须覆盖 onClick 方法：

@Override
public void onClick(View v) {
//Do needful on button press
}

Answer 2

您的应用是否有权使用相机和存储？（清单，询问用户... - https://developer.android.com/training/permissions/requesting.html?hl=es-419）
