Android自定义布局弹窗

弹窗在应用中经常用到，popwindow什么的都太复杂，最近发现了一种简便的弹窗方式，先看图：

废话不多说，上代码：

Activty:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn = (Button) findViewById(R.id.btn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showMyDialog();
            }
        });

    }

    /**
     * 自定义弹窗
     */
    private void showMyDialog() {
        LayoutInflater mLayoutInflater = LayoutInflater.from(MainActivity.this);
        LinearLayout mDialog = (LinearLayout) mLayoutInflater.inflate(R.layout.dialog_layout, null);

        final Dialog dialog = new AlertDialog.Builder(MainActivity.this).create();
        dialog.show();

        dialog.getWindow().setContentView(mDialog);

        mDialog.findViewById(R.id.yes).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "确定", Toast.LENGTH_SHORT).show();
                dialog.dismiss();
            }
        });

        mDialog.findViewById(R.id.cannel).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();
                dialog.dismiss();
            }
        });
    }
}

****注意：AlertDialog导包是import android.app.AlertDialog， 
                而不是import android.support.v7.app.AlertDialog;****
