为什么我的 OnClickListener 实现不起作用？

Question

据我所知，我的 OnClick 方法内部没有任何工作，我也不知道为什么。我正在使用模拟器来测试代码。页面正确加载并且有两个按钮。正如在代码中看到的那样，我会记录做一个信息日志，根据按下的按钮说两件不同的事情。我还尝试在布局中添加 android:clickable="true" 。代码如下：

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class UserOnboardActivity extends ActionBarActivity implements OnClickListener {

    private Button selectMaleAvtr;
    private Button selectFemaleAvtr;

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

        selectMaleAvtr = (Button)findViewById(R.id.select_male_avatar_btn);
        selectFemaleAvtr = (Button)findViewById(R.id.select_female_avatar_btn);

        selectMaleAvtr.setOnClickListener(this);
        selectFemaleAvtr.setOnClickListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_user_onboard, menu);
        return true;
    }

    @Override
    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();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onClick(View v) {
        Log.i("whaaat", v.toString());
        Log.i("whaaat", "hello");
        Toast.makeText(getApplicationContext(), "1", Toast.LENGTH_LONG)
                .show();
        if(v==selectMaleAvtr) {
            Log.i("UserOnboardActivity", "male avatar button pressed");
        } else if (v==selectFemaleAvtr) {
            Log.i("UserOnboardActivity", "female avatar button pressed");
        }
    }
}

XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

        android:text="Next"
        android:id="@+id/button"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

Answer 1

我想问题是您必须查找 viewid 而不是视图本身：

您可以：

public void onClick(View v) {
        Log.i("whaaat", v.toString());
        Log.i("whaaat", "hello");
        Toast.makeText(getApplicationContext(), "1", Toast.LENGTH_LONG)
                .show();
        if(v.getId()==R.id.selectMaleAvtr) {
            Log.i("UserOnboardActivity", "male avatar button pressed");
        } else if (v.getId()==R.id.selectFemaleAvtr) {
            Log.i("UserOnboardActivity", "female avatar button pressed");
        }
    }

或

public void onClick(View v) {
    switch (v.getId()) {

    case R.id.selectMaleAvtr:
        // Things you want do
        break;

    case R.id.selectFemaleAvtr:
        // Things you want to do
        break;

    default:
        break;
    }

}

Answer 2

问题是我使用不同的 activity 打开视图，所以此 activity 中的代码从未被加载。我是用一个intent然后startActivity来解决问题的。

为什么我的 OnClickListener 实现不起作用？

Why isnt my implementation of OnClickListener working?

java

android

onclick
