Question

自定义警报对话框宽度不适合屏幕尺寸，我尝试了很多方法，认为这没什么用（警告对话框宽度应该完全适合屏幕尺寸）如果您有任何建议，请考虑这个请分享你的想法。

import android.app.Activity;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
import android.widget.RelativeLayout;

public class Sample extends Activity {

final Context context = this;
Button btn;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple);

    btn = (Button) findViewById(R.id.buttonShowCustomDialog);
    btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            // custom dialog
            final Dialog dialog = new Dialog(context);
            dialog.setContentView(R.layout.research);
            dialog.setTitle("Title...");
            dialog.show();

        }
    });
}
}

</RelativeLayout>

Answer 1

将此添加到您的style.xml文件中

  <style name="dialog_theme" parent="android:style/Theme.Dialog">
        <item name="android:windowMinWidthMajor">90%</item>
        <item name="android:windowMinWidthMinor">90%</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="android:windowBackground">@android:color/transparent</item>
    </style>

然后将其添加到对话框初始化位置

final Dialog dialog = new Dialog(context, R.style.dialog_theme);
dialog.setContentView(R.layout.research);
dialog.setTitle("Title...");
dialog.show();

Answer 3

只需使用WindowManager.LayoutParams（）

即可

final Dialog dialog = new Dialog(getActivity());
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setContentView(R.layout.research);
            WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
            lp.copyFrom(dialog.getWindow().getAttributes());
            lp.width = WindowManager.LayoutParams.MATCH_PARENT;
            lp.height = WindowManager.LayoutParams.MATCH_PARENT;

            dialog.show();
            dialog.getWindow().setAttributes(lp);

Answer 4

使用dialog.getWindow（）。setLayout（SCREEN_WIDTH，SCREEN_HEIGHT）;

Answer 5

试试这个：

你的res / values / styles中的

：

 <style name="dialog_style" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

现在，在您的活动中，使用以下代码显示对话框：

     final Dialog dialog = new Dialog(Sample.this,R.style.dialog_style);
     dialog.setContentView(R.layout.research);
     dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PA‌RENT, ViewGroup.LayoutParams.MATCH_PARENT); 
     dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); 
     dialog.setCancelable(true);
     dialog.setCanceledOnTouchOutside(true);
     dialog.show();

此处ViewGroup.LayoutParams.MATCH_PARENT将填充屏幕宽度
