Question

如果我按一个按钮然后按另一个按钮，则两个TextView上的数量相加。我希望它们是单独的数字。我试过谷歌找到解决方案，但我找不到任何东西。请帮帮忙？

public class MainActivity extends Activity {

    int clicked = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_main);


            {
                final TextView text = (TextView) findViewById(R.id.textView2);
                final ImageButton button = (ImageButton)findViewById(R.id.imageButton2);
                button.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        clicked++;
                        text.setText("  " + clicked + " ");

                    }
                });
            }

            final TextView text = (TextView) findViewById(R.id.textView1);
            text.setText("");
            final ImageButton button = (ImageButton)findViewById(R.id.imageButton1);
            button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                clicked++;
                text.setText("  " + clicked + " ");

            }


        });

    }

}

使用两个不同的变量。当您按任一按钮时，单击被添加到。同时为按钮选择不同的名称，不要将它们都命名为按钮。

例如：

public class MainActivity extends Activity {

int clicked1 = 0;
int clicked2 = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_main);


        {
            final TextView text = (TextView) findViewById(R.id.textView2);
            final ImageButton button2 = (ImageButton)findViewById(R.id.imageButton2);
            button.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    clicked2++;
                    text.setText("  " + clicked2 + " ");

                }
            });
        }

        final TextView text = (TextView) findViewById(R.id.textView1);
        text.setText("");
        final ImageButton button1 = (ImageButton)findViewById(R.id.imageButton1);
        button.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            clicked1++;
            text.setText("  " + clicked1 + " ");

        }


    });

}

}

我想创建两个按钮，用于添加不同的数字
