android之实现各个组件点击事件监听

注意：（TextView这个组件要点击产生效果的话，要设置，android:clickable="true"这个属性）

布局：layout/activity_main.xml
<LinearLayout 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:orientation="vertical">

<TextView

android:id="@+id/tv"

android:text="点击变字体颜色"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:clickable="true"

/>

<ImageView

android:id="@+id/iv"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:src="@drawable/ic_launcher"

/>

<RadioGroup

android:id="@+id/rg"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="horizontal">

<RadioButton

android:id="@+id/rbMale"

android:text="男"

android:checked="true"

/>

<RadioButton

android:id="@+id/rbfaMale"

android:text="女"/>

<CheckBox

android:id="@+id/cbMale"

android:text="变男"/>

<CheckBox

android:id="@+id/cbfaMale"

android:text="变女"/>

</RadioGroup>

</LinearLayout>

java类：

import android.graphics.Color;

import android.os.Bundle;

import android.util.Log;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.CheckBox;

import android.widget.ImageView;

import android.widget.RadioButton;

import android.widget.RadioGroup;

import android.widget.RadioGroup.OnCheckedChangeListener;

import android.widget.TextView;

public class MainActivity extends ActionBarActivity {

private RadioButton rbMale ;//初始化-----男

private RadioButton rbfaMale ;//初始化------女

private RadioGroup rg;

private TextView tv;

private ImageView iv;

private CheckBox cbMale;

private CheckBox cbfaMale;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

init();

setListener();

}

private void setListener() {

// TODO Auto-generated method stub

cbMale.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View view) {

// TODO Auto-generated method stub

rbMale.setChecked(((CheckBox)view).isChecked());

rbfaMale.setChecked(!((CheckBox)view).isChecked());

}

});

cbfaMale.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View view) {

rbMale.setChecked(!((CheckBox)view).isChecked());

rbfaMale.setChecked(((CheckBox)view).isChecked());

}

});

tv.setOnClickListener(new OnClickListener(){

@Override

public void onClick(View view) {

// TODO Auto-generated method stub

TextView tv = (TextView)view;

tv.setTextColor(Color.RED);

}

});

iv.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View view) {

// TODO Auto-generated method stub

ImageView iv = (ImageView)view;

iv.setImageResource(R.drawable.p01);

}

});

}

private void init(){//初始化 ----男，女

rbMale = (RadioButton) findViewById(R.id.rbMale);

rbfaMale = (RadioButton) findViewById(R.id.rbfaMale);

rg = (RadioGroup)findViewById(R.id.rg);

tv = (TextView)findViewById(R.id.tv);

iv = (ImageView)findViewById(R.id.iv);

cbMale = (CheckBox)findViewById(R.id.cbMale);

cbfaMale = (CheckBox)findViewById(R.id.cbfaMale);

}

}
