Android按钮监几种方法
-------------------第一种，所有按钮受监听.
package gongzibai.co.cc;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
public class RE1Activity extends Activity implements
OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button mButton = (Button) findViewById
(R.id.button1);
Button mButton2 = (Button) findViewById
(R.id.button2);
TextView mTextView = (TextView) findViewById
(R.id.textView1);
mButton.setOnClickListener(this);
mButton2.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(RE1Activity.this, "1000",
2000).show();
}
}
----------------内部监听
public class AnonymousListener extends Activity
{
EditText show;
Button bn;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
show = (EditText)findViewById(R.id.show);
bn = (Button)findViewById(R.id.bn);
//直接使用Activity作为事件易做图
bn.setOnClickListener(new OnClickListener()
{
//实现事件处理方法 www.zzzyk.com
@Override
public void onClick(View v)
{
// TODO Auto-generated method
stub
show.setText("bn按钮被单击了！");
}
});
}
}
-----------依靠XML
<Button
android:id="@+id/button5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="button5"
android:text="Button" />
public void button5(View v)
{
Toast.makeText(RE1Activity.this, "button5",
2000).show();
}
-------------外部监听
mButton4.setOnClickListener(LOVEYOU);}括号外建立
OnClickListener LOVEYOU = new Button.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(RE1Activity.this, "50000",
2000).show();
}
};
---------------------监听方法
OnClickListener LOVEYOU;
LOVEYOU = new Button.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(RE1Activity.this, "50000", 2000).show();
}
};
mButton4.setOnClickListener(LOVEYOU);
