单击任何EditText时屏幕向上滚动

标签： android layout scroll android-edittext

我有一个带有4个EditText的屏幕，如menuName，DishName，Tag和Price 我需要在点击它时将标签Edittext设置在顶部（+ 56dip）。现在它工作正常。

当我点击Tag EditText时，它会像我想要的那样向上移动。

我坚持的地方

移动布局工作正常但是如果我点击其他EditText那么它也会向上移动，我不想要。当我点击Tag EditText时，我只是想滚动屏幕。

这是我的java代码。 

    final View activityRootView = findViewById(R.id.RelativeAdd);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
            new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    int heightDiff = activityRootView.getRootView()
                            .getHeight() - activityRootView.getHeight();
                    Log.i("TEST",
                            "GLOBAL LAYOUT " + activityRootView.getHeight());
                    Log.i("TEST", "GLOBAL LAYOUT rel"+ relativeLayoutHeight);
                    if (heightDiff > 100) { // if more than 100 pixels, its
                                            // probably a keyboard...
                        performScrollingUp();
                        Log.i("TEsT", "Keyboard visible");
} else {
    Log.i("TEsT", "Keyboard not visible");
    performScrollingDown();
    txtDishTags.setDropDownHeight(ViewGroup.LayoutParams.FILL_PARENT);
}
}
});      
     protected void performScrollingUp() {
    if (!isTagUp) {
        txtDishTags.setCursorVisible(true);
        txtDishTags.setFocusable(true);
        txtDishTags.setFocusableInTouchMode(true);
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        inputMethodManager.showSoftInput(txtDishTags, 0);

        firstRelativeLayout.setVisibility(View.GONE);
        secondRelativeLayout.setVisibility(View.GONE);
        firstLinearLayout.setVisibility(View.GONE);
        secondLinearLayout.setVisibility(View.GONE);

        rlp = new RelativeLayout.LayoutParams(
                LayoutParams.FILL_PARENT,
                android.app.ActionBar.LayoutParams.WRAP_CONTENT);
        rlp.addRule(RelativeLayout.BELOW, R.id.tempRelativeLayout);
        tagRelativeLayout.setLayoutParams(rlp);
        isTagUp = true;
        final float scale = getResources().getDisplayMetrics().density;
        int width = (int) (60 * scale + 0.5f);
        int height = (int) (44 * scale + 0.5f);
        rlp2 = new RelativeLayout.LayoutParams(width, height);
        rlp2.addRule(RelativeLayout.BELOW, R.id.tempRelativeLayout);
        rlp2.setMargins(24, 0, 0, 0);
        thirdRelativLayout.setLayoutParams(rlp2);
        lbltag.setGravity(Gravity.CENTER);

    }

}

在可以解决此问题的AndroidManifest.xml中

    <activity 
        android:name="com.example.mainActivity"
        android:windowSoftInputMode="adjustPan">
    </activity>

答案 1 :(得分：2)

您的代码仅在执行heightDiff之前检查performScrollingUp()超过100，并且您的注释表明当键盘弹出时可能会发生这种情况。那么当你点击任何editText字段时，会弹出一个键盘......

修复：

尝试将您的第一个代码块更改为：

final View activityRootView = findViewById(R.id.RelativeAdd);
EditText tagEditText = findViewById(R.id.txtTags);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
            new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {
                    int heightDiff = activityRootView.getRootView()
                            .getHeight() - activityRootView.getHeight();
                    Log.i("TEST",
                            "GLOBAL LAYOUT " + activityRootView.getHeight());
                    Log.i("TEST", "GLOBAL LAYOUT rel"+ relativeLayoutHeight);
                    if (heightDiff > 100 && tagEditText.isFocused()) { // if more than 100 pixels, its
                                            // probably a keyboard...
                        performScrollingUp();
                        Log.i("TEsT", "Keyboard visible");
} else {
    Log.i("TEsT", "Keyboard not visible");
    performScrollingDown();
    txtDishTags.setDropDownHeight(ViewGroup.LayoutParams.FILL_PARENT);
}
}
});

这将确保它只在tagEditText是单击的而不是其他的时向上滚动。现在，您只是在听取整个布局的变化。如果有效，请告诉我。

答案 2 :(得分：1)

我不确定这是否有效。但我至少会这样做：

if (heightDiff > 100) { // if more than 100 pixels, its
                                            // probably a keyboard...
    if(!isTagUp)
        performScrollingUp();
    Log.i("TEsT", "Keyboard visible");
    isTagUp = true; // Keyboard is up
} else {
    Log.i("TEsT", "Keyboard not visible");

    if(isTagUp)
    {
        performScrollingDown();
        txtDishTags.setDropDownHeight(ViewGroup.LayoutParams.FILL_PARENT);
    }
    isTagUp = false; // Keyboard is down again
}

这样甚至不会调用该函数。可能不会解决它，但试一试..
