Android中自定义圆角的Dialog

效果图：

核心代码：

MainActivity中

public class MainActivity extends Activity {
    private Button btn;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn = (Button) findViewById(R.id.btn);


        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showLoginDialog();
            }
        });

    }

    private void showLoginDialog() {
        View view = getLayoutInflater().inflate(R.layout.dialog_layout, null);
        final TextView tvTitle = (TextView) view.findViewById(R.id.tvTitle);
        tvTitle.setText("删除地址");
        final TextView btnYes = (TextView) view.findViewById(R.id.f_quchecbutton_btn_queding);
        final TextView btlNo = (TextView) view.findViewById(R.id.f_quchecbutton_btn_quxiao);
        final MyDialog builder = new MyDialog(MainActivity.this,0,0,view,R.style.DialogTheme);

        builder.setCancelable(false);
        builder.show();
        //设置对话框显示的View
        //点击确定是的监听
        btnYes.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                Toast.makeText(MainActivity.this, "确定按钮。。。", Toast.LENGTH_SHORT).show();
                builder.cancel();
            }
        });


        btlNo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "取消按钮。。。", Toast.LENGTH_SHORT).show();
                builder.cancel();
            }
        });

    }
}

MainActivity布局文件activity_main.xml

自定义MyDialog 

public class MyDialog extends Dialog {
//    style引用style样式
    public MyDialog(Context context, int width, int height, View layout, int style) {

        super(context, style);

        setContentView(layout);

        Window window = getWindow();

        WindowManager.LayoutParams params = window.getAttributes();

        params.gravity = Gravity.CENTER;

        window.setAttributes(params);
    }
}

MyDialog对应的布局文件

res----drawable----bg_dialog.xml设置圆角

res----values----styles.xml设置dialog的样式
