Question

我正在尝试学习Android。我想构建一个简单的字母计数应用程序来计算随机名称，这是我的代码我有onclickListerner的问题。提前感谢您Counting Themed Game

public class MainActivity extends Activity  implements OnClickListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button b = (Button)findViewById(R.id.button1);
    TextView nameView = (TextView)findViewById(R.id.nameView);
    nameView.setText("saya");
    b.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            public boolean onCreateOptionsMenu(Menu menu) {
                getMenuInflater().inflate(R.menu.main, menu);
                return true;
            }

            public boolean onOptionsItemSelected(MenuItem item) {
                // Handle action bar item clicks here. The action bar will
                // automatically handle clicks on the Home/Up button, so long
                // as you specify a parent activity in AndroidManifest.xml.
                int id = item.getItemId();
                if (id == R.id.action_refresh) {
                    TextView nameView = (TextView)findViewById(R.id.nameView);
                    nameView.setText("van");
                }
                return super.onOptionsItemSelected(item);

            }






        }
    });
}

Answer 1

替换它：

b.setOnClickListener() ;

有了这个：

button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                //Your code here
            }
        });

删除它：

@Override
public void onClick(DialogInterface dialog, int which) {
    // TODO Auto-generated method stu
}

Answer 2

由于您要扩展onclicklistener，因此应调用b.setOnClickListener(this);
