九種對(duì)話框.png

基本的 alertdialog 使用

public class MainActivity extends Activity {
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button buttonNormal = (Button) findViewById(R.id.button_normal);
        buttonNormal.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showNormalDialog();
            }
        });
    }
     
    private void showNormalDialog(){
        /* @setIcon 設(shè)置對(duì)話框圖標(biāo)
         * @setTitle 設(shè)置對(duì)話框標(biāo)題
         * @setMessage 設(shè)置對(duì)話框消息提示
         * setXXX方法返回Dialog對(duì)象，因此可以鏈?zhǔn)皆O(shè)置屬性
         */
        final AlertDialog.Builder normalDialog = 
            new AlertDialog.Builder(MainActivity.this);
        normalDialog.setIcon(R.drawable.icon_dialog);
        normalDialog.setTitle("我是一個(gè)普通Dialog")
        normalDialog.setMessage("你要點(diǎn)擊哪一個(gè)按鈕呢?");
        normalDialog.setPositiveButton("確定", 
            new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //...To-do
            }
        });
        normalDialog.setNegativeButton("關(guān)閉", 
            new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //...To-do
            }
        });
        // 顯示
        normalDialog.show();
    }
}

3 個(gè)按鈕

/* @setNeutralButton 設(shè)置中間的按鈕
 * 若只需一個(gè)按鈕，僅設(shè)置 setPositiveButton 即可
 */
private void showMultiBtnDialog(){
    AlertDialog.Builder normalDialog = 
        new AlertDialog.Builder(MainActivity.this);
    normalDialog.setIcon(R.drawable.icon_dialog);
    normalDialog.setTitle("我是一個(gè)普通Dialog").setMessage("你要點(diǎn)擊哪一個(gè)按鈕呢?");
    normalDialog.setPositiveButton("按鈕1", 
        new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // ...To-do
        }
    });
    normalDialog.setNeutralButton("按鈕2", 
        new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // ...To-do
        }
    });
    normalDialog.setNegativeButton("按鈕3", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // ...To-do
        }
    });
    // 創(chuàng)建實(shí)例并顯示
    normalDialog.show();
}
