Question

是的，这是多方面的问题，但没有一种方法可行。

我正在尝试将对话框宽度扩展到全屏。

对话框布局：

对话框代码：

        val inflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        val dialogView = inflater.inflate(R.layout.mobile_bottom_sheet_layout, null)

        val phone = dialogView.findViewById<EditText>(R.id.userPhone)
        dialogBuilder.setView(dialogView)
        val alertDialog = dialogBuilder.create()

        val countinueButton = dialogView.findViewById<Button>(R.id.continueButton) as Button

        countinueButton.setOnClickListener {

            if(phone.text.toString().isEmpty()){
                phone.error=getString(R.string.empty)
                phone.requestFocus()
            }else if(phone.text.toString().length!=13){
                phone.error=getString(R.string.phone_length_error)
                phone.requestFocus()
            }else{

                checkIfTrainerExists(phone.text.toString(),this@LoginActivity);
            }

        }

        alertDialog.show()

我也尝试了其他解决方案。但没有一个有效。

Answer 1

您可以创建自定义FragmentDialog并执行

@Override
public void onResume() {
    // Resize the dialog to full screen.
    if (getDialog() != null && getDialog().getWindow() != null) {
        Window window = getDialog().getWindow();
        window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
    }
    super.onResume();
}

Answer 2

查看此示例Full Width Dialog。这可能会对你有帮助。

Answer 3

试试这个

制作自定义对话框组件

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.support.annotation.NonNull;

public class CustomDialog extends Dialog {

     public CustomDialog(@NonNull Context context) {
        super(context);
    }

    public CustomDialog(@NonNull Context context, int themeResId) {
        super(context, themeResId);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_layout);// use your layout in place of this.

    }
}

在下面写下您想要的代码。

CustomDialog dialog=new CustomDialog(MainActivity.this, android.R.style.Theme_Material_Light_NoActionBar_Fullscreen);
                dialog.show();

Answer 4

尝试使用Dialog代替AlertDialog，以便您可以根据需要创建自定义对话框。

你也可以：

public class CustomDialog extends Dialog{

    public void onCreate(Bundle savedInstance) {

        super.onCreate(savedInstance);

        setContenctView(R.layout.custom_layout);

        // You can manipulate the Dialog using         
        //Window window = getDialog().getWindow();


    }      

}

Answer 5

对于kotlin中的简单AlertDialog，您可以使用

alertDilog.getWindow().setLayout(
                LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT)

在alertDilog.show()

之后

此处AlertDialog为android.support.v7.app.AlertDialog

Answer 6

如果使用ConstraintLayout，它将无法正确匹配匹配约束。为了获取布局参数，请在 onAttachedToWindow 方法上应用它们。

class DialogDownloadFinished(context : Context) : Dialog(context) {

    override fun onCreate(savedInstanceState: Bundle?) {
       super.onCreate(savedInstanceState)
       val dialogView =  DialogDownloadFinishedBinding.inflate(LayoutInflater.from(context),null,false)
       requestWindowFeature(Window.FEATURE_NO_TITLE)
       setContentView(dialogView.root)
    }

    override fun onAttachedToWindow() {
       super.onAttachedToWindow()
       window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
       window.setGravity(Gravity.TOP)
    }
}
