最近有个项目是没有触摸的,外接的16键硬件键盘,但EditText在获取焦点时还是会弹出输入法。
不想对每个EditText都设置监听处理。有没有更优雅的方法能让程序在运行期间都不会弹出输入法?最好是只要配置一下AndroidManifest.xml或者在Application里面运行一段代码。

The global theme style used in your AndroidManifest.xml should look like this:

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">//使用的是AppTheme主题样式

Then what you need to do is, in the AppTheme中设置 EditText style, the complete styles.xml is as follows:

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="editTextStyle">@style/NoFocusableEditText</item>
    </style>

    <style name="NoFocusableEditText" parent="Widget.AppCompat.EditText">
        <item name="android:focusable">false</item>//没有焦点就不会弹出了
    </style>

In this way, the EditText of the entire App is set.

/-----------------------Since the questioner added a description based on the question, I updated the answer as follows---------- ---------------/
Add the following code in the onCreate function of your Activity to completely disable the soft keyboard:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);

So, if you want it to take effect globally, you can write a base class, for example:

public abstract class BaseNoIMActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
        onCreateStarted(savedInstanceState);
    }

    protected abstract void onCreateStarted(@Nullable Bundle savedInstanceState);
}

Then any Activity inherits it. If your project already has a base class, just insert the above code into the base class. Demo example:

public class TestActivity extends BaseNoIMActivity {//继承基类

    @Override
    protected void onCreateStarted(@Nullable Bundle savedInstanceState) {
        setContentView(R.layout.activity_test);
        Log.e("test","TestActivity is started");
    }
}
