菜单PopupMenu和对话框AlertDialog、进度条对话框PopupWindow用法相关例子和自己写的案例
菜单
第一步：创建弹出菜单对象
PopupMenu popupMenu = new PopupMenu(Context context, View anchor);
第一个参数view.cantext 始终可以得到一个cantext，第二个参数view弹出菜单的显示位置，显示在view的下面
第二步：载入菜单的布局文件
popupMenu.getMenuInflater().inflate(menuRes, menu)
第一个参数是布局文件的路劲（R.menu.item），第二个参数是popupMenu.getMenu()
只能载入文字的布局文件，不能带有图片（无法显示）
第三步：可设置监听器
OnMenuItemClickListener
package text.act;
import android.app.Activity;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.PopupMenu;
import android.widget.TextView;
public class MainActivity extends Activity {
private Button button;
private TextView textView1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.activity_main);
this.button = (Button) findViewById(R.id.button);
this.textView1 = (TextView) findViewById(R.id.textView1);
this.button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
/**创建弹出菜单对象 PopupMenu(Context context, View anchor)
* 第2个参数view作用：弹出菜单显示在view的下面
*/
PopupMenu popupMenu = new PopupMenu(MainActivity.this, textView1);
//为弹出菜单加载菜单项xml配置文件(res/menu/item.xml)
popupMenu.getMenuInflater().inflate(R.menu.item, popupMenu.getMenu());
//为弹出菜单设置监听器(可选)
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem menuItem) {//menuItem菜单项对象
int id = menuItem.getItemId();//得到被点击菜单项的id
if(id == R.id.close) {
MainActivity.this.textView1.setText("关闭");
}else if(id == R.id.open) {
textView1.setText("打开");
}
return false;
}
});
//显示弹出菜单
popupMenu.show();
}
});
}
}
AlertDialog、PopupWindow、ProgressDialog、DataPickerDialog、TimePickeDialog
alertDialog.cancle 取消对话框
getProgress 读取当前进度
show（）显示
cancle（）取消
dismiss取消
setCancelable（false）禁止用户点击外围时取消显示
PopupWindow的特殊：取消对话框可以在子线程中执行（不增在子线程中操作页面）；
