如果键盘可见，Android布局背景将被压缩 [英] Android layout background get compressed, if keyboard is visible

问题描述

我正在尝试编写代码，以保持布局的大小，即使Softkeyboard可见.但是，每当键盘可见且布局看上去混乱时，布局背景图像就会合并.但是我已经在whatsapp中看到了，即使打开键盘，背景也不会改变它的状态.所以，我不知道这样做的技术.

I am trying to write a code maintain the size of the layout even if Softkeyboard is visible. But the layout background image gets merged whenever keyboard is visble and layout looks cluttered. But i have seen in whatsapp that , even if keyboard is open the background does not change it's state. So , i don't know the technique to do it.

我的代码:

package com.example.testlayout;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends ActionBarActivity {

String[] data = new String[50];

ListView list;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    getWindow().setBackgroundDrawableResource(R.drawable.image_bgswitch);
    list = (ListView) findViewById(R.id.listView1);


    for(int i=0;i<50;i++){
        data[i] = "";
    }

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
              android.R.layout.simple_list_item_1, android.R.id.text1, data);
    list.setAdapter(adapter);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
} }

XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.testlayout.MainActivity" >

<ListView
    android:id="@+id/listView1"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_alignParentTop="true"
    android:layout_marginTop="0dp" >

</ListView>

<EditText
    android:id="@+id/editText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:ems="10" />

清单:

<?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testlayout"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="21" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:windowSoftInputMode="adjustResize">

          <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

屏幕截图: 键盘不可见

键盘可见

这些是我的问题的上述代码和屏幕截图，请向我建议即使键盘可见，也可以保持背景原样的技术.

These are the above codes and screenshots of my issue , please suggest me the technique to keep background as it is even if keyboard is visible.

推荐答案

在清单中将android:windowSoftInputMode从adjustResize更改为adjustNothing

 <activity
            android:name=".MainActivity"
            android:windowSoftInputMode="adjustNothing">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
 </activity>
