Dialog的使用

看了SDK,写了这几个例子。

代码如下:

package com.chaowen;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.app.AlertDialog.Builder;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class DialogActivity extends Activity {
private Button dialog1,dialog2,dialog3,dialog4,dialog5,dialog6,dialog7;
@Override
public void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
setContentView(R.layout.main);
dialog1 = (Button)findViewById(R.id.button01);
dialog2 = (Button)findViewById(R.id.button02);
dialog3 = (Button)findViewById(R.id.button03);
dialog4 = (Button)findViewById(R.id.button04);
dialog5 = (Button)findViewById(R.id.button05);
dialog6 = (Button)findViewById(R.id.button06);
dialog7 = (Button)findViewById(R.id.button07);


dialog1.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity. this );
builder.setMessage( " 这是一个简单的对话框 " )
.setCancelable( false )
.setPositiveButton( " 确定 " , new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(DialogActivity. this , " 你按了确定 " , Toast.LENGTH_LONG).show();

}
})
.setNegativeButton( " 取消 " , new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(DialogActivity. this , " 你按了取消 " , Toast.LENGTH_LONG).show();

}
});
AlertDialog alert = builder.create();
alert.show();
}
});


dialog2.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
final CharSequence[] items = { " Red " , " Green " , " Blue " };
AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity. this );
builder.setTitle( " 选择颜色 " );
builder.setItems(items, new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int item) {
Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_LONG).show();

}
});
AlertDialog alert = builder.create();
alert.show();
}
});


dialog3.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
final CharSequence[] items = { " Red " , " Green " , " Blue " };
AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity. this );
builder.setTitle( " 选择颜色 " );
builder.setSingleChoiceItems(items, - 1 , new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int item) {
Toast.makeText(getApplicationContext(), items[item],Toast.LENGTH_LONG).show();

}
});

AlertDialog alert = builder.create();
alert.show();
}
});

dialog4.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
ProgressDialog dialog = ProgressDialog.show(DialogActivity. this , " 这是一个圆形处理条 " ,
" Loading. Please wait... " , true );

}
});


dialog5.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
ProgressDialog pd = new ProgressDialog(DialogActivity. this );
pd.setTitle( " 这是一个水平进度条 " );
pd.setMessage( " Load..... " );
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.setCancelable( true );
pd.show();
}
});


// 自定义处理条一
dialog6.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext = DialogActivity. this ;
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog, (ViewGroup)findViewById(R.id.layout_root));


TextView text = (TextView) layout.findViewById(R.id.text);
text.setText( " Hello, this is a custom dialog! " );
ImageView image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
alertDialog.show();
}
});


// 自定义处理条二
dialog7.setOnClickListener( new OnClickListener() {

@Override
public void onClick(View v) {
Context mContext = DialogActivity. this ;
Dialog dialog = new Dialog(mContext);

dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle( " Custom Dialog " );

TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText( " Hello, this is a custom dialog! " );
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);
dialog.show();
}
});
}


}
