AlertDialog 不包装我的内容

Question

我正在使用警报对话框显示带有微调器的视图以设置图表的周期和比例

但它没有包装我的内容，我尝试的所有 tuto 都失败了......

我的代码

        LinearLayout vue = new LinearLayout(context);
        vue.setOrientation(LinearLayout.VERTICAL);
        vue.addView(diag.getView());

        choixPeriode = (Spinner) vue.findViewById(R.id.spinner_periode);
        choixEchelle = (Spinner) vue.findViewById(R.id.spinner_echelle);
        if(choixEchelle == null)
            choixEchelle = new Spinner(context);
        final int oldPeriode = DiagramController.PeriodeToPos(this.periode);
        final int oldEchelle = DiagramController.echelleToPos(this.echelle);
        choixPeriode.setSelection(oldPeriode);
        choixEchelle.setSelection(oldEchelle);


        LinearLayout containerButton = new LinearLayout(context);
        containerButton.setGravity(Gravity.CENTER);

        final ImageView croix = ((ImageView) vue.findViewById(R.id.croix));
        final Button ok = new Button(context);
        ok.setText(R.string.valider);
        final Button cancel = new Button(context);
        cancel.setText(android.R.string.cancel);

        containerButton.addView(ok);
        containerButton.addView(cancel);

        vue.addView(containerButton);

        AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(context);
        dialogBuilder.setView(vue);

        final AlertDialog alertDialog = dialogBuilder.create();
        WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
        lp.copyFrom(alertDialog.getWindow().getAttributes());
        lp.width = WindowManager.LayoutParams.WRAP_CONTENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        alertDialog.getWindow().setAttributes(lp);
        alertDialog.show();

        croix.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                alertDialog.dismiss();
            }
        });

        ok.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                periode = DiagramController.posToPeriode(choixPeriode.getSelectedItemPosition());
                echelle = DiagramController.posToEchelle(choixEchelle.getSelectedItemPosition());
                changePeriode();
                alertDialog.dismiss();
            }
        });

        cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                alertDialog.dismiss();
            }
        });

diag.getView() 返回带有标题、微调器和图表的 LinearLayout。

结果为纵向

结果为横向

自定义对话框的结果

Answer 1

1.) 您需要创建自定义 xml 布局。

2.) 创建一个新类。并在 onCreate 中编写您的代码。

public class MyDialog extends Dialog {

private TextView textView;

private Context context;

public MyDialog(Context context) {
    super(context);

    this.context = context;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.my_layout);

    //Your code
    textView = (TextView) findViewById(R.id.textView);


}
}
