Dialog全屏，一行代码搞定

第一步，自定义一个Dialog继承自Dialog；

第二步，在设置setContentView(R.layout.dialog_your_layout)后 调用以下代码

getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);//设置Dialog为全屏

/***************************************我是分隔线********************************************/

public class UploadImageDialog extends Dialog {


    private Context mContext;
    public TextView tvAlbum;
    public TextView tvCamera;
    public TextView tvCancell;

    private View view;

    public UploadImageDialog(Context context, int themeResId) {
        super(context, themeResId);
        this.mContext = context;
        initView();
    }

    private void initView() {
        setContentView(R.layout.dialog_uploadimage);
        getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);//设置Dialog为quan  tvAlbum = (TextView) findViewById(R.id.m_tv_dialog_album);
        tvCamera = (TextView) findViewById(R.id.m_tv_dialog_camera);
        tvCancell = (TextView) findViewById(R.id.m_tv_dialog_cancel);
        view = findViewById(R.id.m_view_divider);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
    }
