您好,我在设置对话框大小以适合窗口宽度时遇到问题。
我在这里尝试了以下几种答案: Android dialog width Android get full width for custom Dialog
但是我无法达到手机宽度的全部大小。它实际上具有TOP(重力)的属性,但宽度却没有。
我使用的代码是:
package bem.banorte.bem;
import android.app.Activity;
import android.app.Dialog;
import android.graphics.Color;
import android.graphics.Point;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.view.ContextThemeWrapper;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.TextView;
/**

public class ThirdActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.CustomDialogTheme));
TextView title = new TextView(this);
// You Can Customise your Title here
title.setText("Error en la aplicacion");
// title.setBackgroundColor(Color.);
title.setPadding(0, 30, 0, 30);
title.setGravity(Gravity.CENTER);
title.setTextColor(Color.WHITE);
title.setTextSize(20);
builder.setCustomTitle(title);
//antes era alertDialog
Dialog dialog = builder.create();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(true);
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
lp.gravity = Gravity.TOP | Gravity.LEFT;
lp.x = 0; //x position
lp.y = 85; //y position
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
dialog.show();
dialog.getWindow().setAttributes(lp);
}
}
样式的代码是这样的:
<style name="CustomDialogTheme" parent="@android:style/Theme.Dialog">
<item name="android:textColor">@color/black</item>
<item name="android:windowBackground">@color/warningA</item>
<item name="android:background">@color/warningA</item>
<item name="android:windowIsFloating">false</item>
<item name="android:typeface">normal</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
</style>
活动如下:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="bem.banorte.bem.ThirdActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"
android:orientation="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="1.0">
</LinearLayout>
</android.support.constraint.ConstraintLayout>
答案 0 :(得分:1)
在对build.gradle和所有OP进行交叉检查之后,这似乎是设备特定的问题。这段代码在Nexus 5(api 23)真实设备和Pixel2(Api 23)AVD中不会占用全角。
我们怀疑-@android:style/Theme.Dialog
在此Motorola G Play(Android 6.0.1 api 23)设备中不相同。
您的拨号正在获取完整宽度。我尝试了您的代码,但在您的主题中按照以下方式切换了颜色-
<item name="android:windowBackground">@android:color/holo_blue_light</item>
<item name="android:background">@android:color/holo_red_light</item>
